Councillor Peter Hiller, the city council's cabinet member for growth, planning, housing and economic development, said: "This was an important and necessary improvement programme for a busy junction completed ahead of schedule and on budget.

"Road users will see the benefit to their journey now and, with future housing development to the surrounding area on the horizon, in the future.

"This work was only possible due to funding from the Greater Cambridge Greater Peterborough Local Enterprise Partnership so we would like to thank them for their support of the city.

"We would also like to thank motorists and residents for their patience and understanding while these works have been carried out."

Neil Darwin, Chief Executive of the Greater Cambridge Greater Peterborough LEP, said: "Supporting infrastructure improvements to enable the continued growth of Peterborough is an important part of the work we do here at the LEP.

“We are pleased to have provided funding towards the upgrading of Junction 20 of the A47 – a key route into the city for commuters and visitors alike."
